Calculation of Desuperheater
Calculation of Desuperheater
(OP)
Hi,
I am a new engineer in a chemical industry plant.
When I calculate on the desuperheater with auxiliary steam in our steam reduction station,I run into difficulties. How to make certain the relationship of auxiliary steam and cooling water.So I can calculate the flux of auxiliary steam and cooling water.
Can you help me?
Thank you.

m1h1 + m2h2 = m3h3

Thank you for reply.

The desuperheater with auxiliary steam is introduce a high pressure steam to enhance the atomizing of cooling water in the nozzle.
I try to solve the auxiliary steam flux and cooling water.
RE: Calculation of Desuperheater
it is not a problem to solve.
RE: Calculation of Desuperheater
The water, however, is controlled and varies with the main steam flow and temperature fluctuations.
If it is the auxiliary steam that you are trying to solve for, no wonder you are stumped. That is not a calculable variable.

I understand.
Could you give me a example of selection of the auxiliary steam flow in a desuperheater.
Thanks.
RE: Calculation of Desuperheater
Could you give me some references or books about relationship of nozzle, pressure and auxiliary steam flux. I have no idea of it.

Those ought to do for a start. By the way, steam assist DSH's are usually picked for a reason and as toothless says above, if the job can be done without using a steam assist, things are much simplier.

I have already contact them. But no one reply to me.
Could you give me some references or theory about relationship of nozzle, pressure and auxiliary steam flux.
